I could have sworn someone posted a thing for this just a week or two
ago, using `org-map-entries' and the identity function, and counting the
results. Anyway look at the docstring for `org-map-entries', it takes a
SCOPE argument you can set to 'tree to just map the headings under the
current one. A stupid example might look like:

(apply '+ (org-map-entries (lambda () 1) t 'tree))

Though that will count the top-level heading, as well.
